Habitat and Ecology [top]

Habitat and Ecology:Habitat includes rocky pools and adjacent riffles of headwaters and creeks (Page and Burr 2011). This darter prefers small quiet streams with large flat rocks or bedrock bottoms; small populations occur in small gravelly streams and in larger streams along quiet margins and beneath undercut banks (Braasch and Mayden 1985). Spawning occurs in cavities under rocks; females attach eggs to undersides of stones (Braasch and Mayden 1985).
Movement patterns:Not a Migrant
